TECHNICAL FIELD

The present invention relates to a portable apparatus for the making and dispensing of frozen alcoholic or nonalcoholic, ice or dairy drinks and to methods for making and using the same.

BACKGROUND OF THE INVENTION

Although a number of frozen drink systems exist they suffer from a number of disadvantages. For example, they are either not portable, do not have a insulated housing, require continuous power, make small quantities, are difficult to maintain or require a relatively considerable amount of time (typically greater than five minutes) to prepare the frozen drink.

Thus there is a need in the art for an improved portable frozen drink dispenser that is simple to operate, insulated and easily maintained.

The present invention relates to a portable apparatus for making and dispensing frozen alcoholic or non alcoholic ice or dairy drinks including: (1) a insulating housing for containing the frozen drink; and (2) a mechanical apparatus for preparing and dispensing the frozen drink.

DETAILED DESCRIPTION OF THE INVENTION

As used herein, “a” or “an” means one or more, unless otherwise indicated. The singular encompasses the plural and the plural encompasses the singular.

The inventors have found that a portable frozen alcoholic or nonalcoholic, ice or dairy drink dispensing apparatus can be manufactured that can make a large quantity of frozen drink in under five minutes and does not require continuous electrical power to maintain the frozen drink.

The present invention relates to a portable frozen alcoholic or nonalcoholic, ice or dairy drink dispensing apparatus that is easily maintained. The apparatus includes an electrically powered mechanical system to prepare and dispense the frozen drink and an insulated housing to maintain the frozen drink. The mechanical system can be either AC (alternating current) or DC (direct current) powered. Preferably, the apparatus includes a safety system to prevent the operation of the apparatus when the top is removed. The raw products used to make the frozen drink can be inserted into the apparatus either through the port in the top, or by removing the top. The frozen drink is prepared by powering the unit for less then five minutes to mix the product. After this time the frozen drink is dispensed using a hand valve that operates the mechanical system and dispenses the frozen drink. In one embodiment of the design, the frozen drink is maintained in the insulated housing without a secondary cooling system. Another embodiment includes a secondary cooling system that would require continuous power to operate. The housing is designed to facilitate the preparation of the frozen drink by several methods to force the product into the mechanical system. This is done through the use of a unitary construction of the mechanical system and the housing, and preferably also through the use of a unique shape of the internal housing. The preferred shape of the internal housing is one having a bullet-shaped inner surface. The mechanical system is design to process the raw products to a consistent texture similar to a more expensive slush or frozen shake machine. This same mechanical system is utilized to dispense the drink on demand by opening a control valve that turns on the mechanical system forcing the frozen drink through the dispenser. Preferably, the system includes a safety feature which prevents operation of the mechanical system should the top be removed from the housing. One way, among others, to accomplish this is through the use of a pressure-activated switch located at the interface between the housing and the top. Other means to accomplish this objective, well known to those of ordinary skill in the art are also useful in the present invention. Preferably, there is also a ground fault interrupt circuit to prevent the operation of the unit should there be an electrical short in the electrical or mechanical system.

Suitable materials for the making of the housing include, without limitation, metals, plastics or other suitable materials or mixture or combinations thereof. Preferably the outer surface can be made of metal such as, but not limited to, stainless steel, galvanized metal, aluminum or plastics such as but not limited to, polyethylene, PVC (polyvinyl chloride) or mixture of combinations thereof. The inner surface of the housing can be made of any food grade material such as but not limited to stainless steel, aluminum, or plastics such as but not limited to polyethylene, PVC or mixture of combinations thereof. The interstitial space between the outer surface and the inner surface can be filed with any insulating material such as but not limited to PVC, polyethylene, polyurethane or other suitable material. The interstitial space can also be evacuated, to prevent heat transfer from the inner to the outer surface. As used herein, the inner surface of the housing is that surface which contacts the frozen drink components. The outer surface of the housing is therefore, the opposite surface.

Suitable material for the making of the mechanical system include, without limitation, stainless steel or other food grade metals for the processing surfaces, and stainless steel, steels, aluminums and plastics for the remainder of the mechanical system.
